I am experiencing lots of problems with transferring files from my computer to my sony device. I never had these problems with the 3.2. I had recently reformatted and went and installed it from the installer file i kept for backing up, and it auto-downloaded 3.4. is there any way i can find/download 3.2? it always worked fine with me. I can't get anything to transfer properly with 3.4 too many error codes etc. i need my music NOW:( any help would be appreciated. my email is minimal_casualties@hotmail.com thanks in advance
